BOX-WRAPPING SYSTEM.

Application filed April 8, 1926. Serial No. 100,475.

My invention relates to a method, and apparatus for applying a wrapper, sheet, label or the like, hereinafter generically termed a wrapper to a box, box structure, packa e, container structure or the like, hereina ter generically termed a box.

In accordance with my invention, engagement of the box-bottom and a section of the wrapper having been properly effected, a portion of awrapper side panel is folded into engagement with the horizontal surface of a box end wall and thereafter another portion of the side panel aforesaid is folded into engagement with the horizontal surface of a box side wall meeting said end wall in a corner.

Further in accordance with my invention, engagement of the box bottom and a section of the wrapper having been effected, as aforesaid, a portion of a wrapper side panel is folded into engagement with the horizontal surface of a box end wall whereupon a corner-lap section comprised in said side panel is folded into engagement with the vertical surface of said end wall and, preferably, during the operation last mentioned the upper portion or extremity of the corner lap section after being subjected to a creasing operation or the like remains temporarily upstanding from which position it is bent or folded and finally assu es a position beneath a portion of the turnn section of a wrapper end panel as said turn-in section is brought into adhering relation with the upper horizontal surface of the box end aforesaid.

Further in accordance with my invention, to a box having side and end walls meeting in a corner and which rise, respectively, different distances from the bdx-bottom there isapplied a wrapper and after a portion of a wrapper side panel has been folded into engagement with the horizontal surface of the box end wall aforesaid, the panel is slit or cut in a direction extending toward the box-bottom, and more particularly, the folding and slitting operation aforesaid is performed substantiall simultaneously.

Further in accor ance with my invention, portions of a wrapper are caused to overlie and adhere to the horizontal surfaces of the walls of a box by a wiping or ironing action.

Further in accordance with my invention, to the portions of a wrapper freshly folded into engagement with the interior surfaces of the box walls there is applied pressure effective from one or more regions within the box for causing intimate engagement between the box walls and wrapper portions aforesaid.

Further in accordance with my invention, the box-wrapping or covering operation is effected automatically in a wrapping machine or the like whose corner-lap mechanism comprises structure for folding a portion of a wrapper into engagement with the horizontal surface of a box wall and for slitting orcutting the wrapper in a direction extending toward the box-bottom.

Further in accordance with my invention, in a wrapping machine as aforesaid there is included novel structure for causing the various turn-in sections of a wrapper to assume horizontal positions above the box walls and bottom, and more particularly, the structure aforesaid wipes or irons portions of the wrapper into engagement with horizontal surfaces of the box walls.

Further in accordance with my invention, the form block structure of a wrapping machine is so constructed that in one position thereof pressure may be applied from directions within the box against wrapper portions freshly folded into engagement with the interior surfaces of the box walls, and more particularly, such pressure-applying mechanism comprises members movable relatively with respect to the form block struc ture under the influence of the automatic mechanism of the wrapping machine.

My invention resides in the method, apparatus, and features or details of constructlon of the character hereinafter described and claimed.

For an illustration of some of the forms my invention may take, reference is to be had to the accompanying drawings in which:

Fig. 17 is a perspective view of a corner lap turnin member equipped with suppleigientary wrapper, folding and slitting mem- Referring to Fig. 1, there is illustrated a wrapper W of suitable material, as paper. It is to be understood that ordinarily wrapper N is a plane flat sheet, cut and notched as indicated, but unscored and uncreased. For purposes of explanation, however, the wrapper is shown as traversed by a lurality of broken lines apparently effecting division thereof into a number of sections.

Accordingly, and as herein shown, the broken lines aforesaid may be assumed to divide wrapper W into a bottom section a and the oppositely disposed end panels b, each of the latter comprising a turn-in section 6 each turn-in section in turn comprising a portion b adapted to lie along the top horizontal surface of one end of the box and a portion 6 adapted to be folded within the box end, the vertical dimension or width of the extremity of portion N, as viewed in Fig. 1, being somewhat less than the corresponding vertical dimenslon of the end panel proper. Also, wrapper W may be assumed to comprise the front side panel 0 and the rear side panel d. Front side panel 0 comprises the turn-in section 0 said turn-in section comprising a portion 0 adapted to lie along the top horizontal surface of the front wall of the box and a portion 0*" adapted to be folded into engagement with the upper interior surface of said front wall of the box. Front side panel 0 also comprises the generally rectangular sections 0 adapted, respectively, to overlie and adhere to portions of the top horizontal surfaces of the end walls of the box at the front thereof, as hereinafter more fully described. Front side panel 0 also comprises the corner lap sections 0 each of the latter in turn comprising a generally rectangular section 0 adapted to be folded into engagement with and in part overlie one of the rectangular sections a aforesaid and the contiguous area of the top horizontal surface of the end wall of the box receiving said section 0.

Rear side panel d comprises the turn-in sections d each of the latter comprising a section at adapted to lie along a portion of the top horizontal surface of the rear wall of the box and a section (l adapted to be folded into engagement with the interior surface of said rear wall of the box. Panel all also comprises the generally rectangular sections d adapted, respectively, to overlie and adhere to portions of the top horizontal surfaces of the end walls of the box at the rear of the box, as hereinafter more fully described. Panel d also comprises the corner lap sections (Z each of the latter comprising a generally rectangular section (I adapted to be folded into engagement with and in part overlie one of the rectangular sections d aforesaid and the contiguous area of the top horizontal surface of the end wall of the box receiving said section (1 It will be observed that turn-in sections (Z1, in

eliminating a rectangular section from the rear side panel 61. As a result a portion of the rear wall of the box remains uncovered by the wrapper.

In Fig. 2, I have illustrated a modified form of wrapper W generally the same as that shown in Fig. 1, differing, however, in that the rectangular sections a comprised in the front panel 0 are each notched as indicated at a. the notches preferably converging toward the center of the wrapper. Likewise, the rectangular sections (1 comprised in the rear panel (I are similarly notched as indicated at d, these notches also preferably converging toward the center of the wrapper.

As indicated in Figs- 5', Wood 7, due to differs from wrapper W of Fig. 1 in that R5 the configuration of the rear ride panel cl, there are provided slits or notches c and d a portion of the rear wall B of the box 112- therein and. accordingly, the former may mains uncovered or unwrapped. whereby be a plied to the box in a manner similar the hinges for the box cover may be secured to t lat described above with respect to B5 in position without disturbing the wrapper. wrapper W except that it s unnecessary to secured to a shaft or slitting operation. In gs. and 5", have illustrated the tion assumed by the notches c' and at one stage of the application of wrapper W to a. box.

The foregoing perform a cuttin wrapping operation or one equivalent therewith may be performed manually. Preferably, however, such oper ation is effected automatically in awrapping machine or unit. of suitable type, for example, as illustrated in Figs. 9, 10, 11, 13-17," inclusive, where there is illustrated a machine or, unit M for wrap ing or covering with a suitable wrap er, a, 1:, one or more of whose faces or we ls IS or are of substantial thickness as a cigar box or the like.

Machine M may be of any type suitable for efl'ecting this epd, for example, of the f eneral character disclosed in U. S. Letters atent to Smith No. 691,329, suitably modified, however, to care for the different conditions resented when wrapping a box of the kind noted above.

As herein shown in Fi 9, machine M comprises a base 1 from w ich rise the legs 2 or the like, to which in turn are secured in spaced rclationthe platform 3 and table 4.

As well understood in the art, clutch 12 may be controlled by a lever 13 14. Upon actuation of lever 13 to rotate its shaft there is effected one cycle of o eration ofthe wrapesingl machine. Also, t iere may be provi a ever 15 for locking the clutch 1n open position and a lever 16 effective, when :aetuatecl, for sto ping the machine at any time.

the former receiving a roller carried b an arm 30 pivoted to an extension 31 o oseneck 5. l A link 32 is pivoted at one on of the free end of arm 80 and at its other end to a yoke 33 carrying the stripper fingers 34 which, at predetermined times, pass through-aligned apertures in the intermediate and upper form blocks 22 and 23 to strip the W111 box therefrom.

Adpmr of paral e uide rods 35 are secure to yoke 33 and respectively extend upward! through a pair of perforated lugs 36 suite 1y secured to plunger 20.

Groove G in com 6 receives a roller carried by an arm 37 pivoted to an extension gooseneck 5, said arm 37 at one end carrying a suitable counter weight 39 and it its other end being pivoted to an arm 40 In turn pivoted to lunger 20.

Extending upwar ly from the base 1 are the collapsi le rods or tubes 41 and 42, tube 42 sliding freely downwardly on the exterior surface of tube 41, and viewed in Fig. 9 against the expansive tendency of a coiled spring 43 or the like. At its upper and tube 42 carries the luten or lower form block 44, between whic and the intermediate form block 22, the box bottom and its aidhering wrapper are at times confined, as hereinafter more fully described.

With clutch member 12 eugu ed with pulley 11, cam 6 will be rotated t rough shaft 7, shaft 10 end the interposed gearin described above. Assuming that the intermediute and upper form blocks 22 and 23 are in their u per region of travel, rotation of cum 6 will ring cum groove G into such relation with the roller on lever 37 that the descent of the intermediate and upper form block structures under the influence of gravit; will be permitted Finally, a box and an a boring wrapper having been placed on the descending form block structure, it will be moved into engagement with the lower form block 44, whereupon the combined form block structure com pri in upper form block- 23, intermediate form hock 22 and lower form block 44 and the box with its wrapper move downwardly through the various instrumentnlities comprised in the wrapping machine. At a predetermined time, a lug, pin or projection, not shown, on cross-head 29 engages a cum, not shown, controlled by com grooves G and lever 30, to prevent further downward movement of the upper form block 23 for the time being. llmncdintcly after downward movement of the upper form block is thus prevented, certain turnin fingers, hereinafter dc=-rribed, move beneuth said form block 23, whereupon the cam aforesuid is -retracted from on 'ugcmcnt with the lug or projection aforesuidi leaving form block 28 supported solely by the turu-in fingers aforesaid. Cum G having performed provided with two cam grooves this function, now remains idle until the form block structures begin their upward return journey, when at a prtper and predetermined time cam groove functions to partially rotate arm 30 in a counter-clockwise direction, as viewed in Fig. 9, to depress yoke 33 and pass the stripper fingers within the apertures in the intermediate and upper form blocks to strip or remove the wrapped box therefrom.

In accordance with my invention, the uppar and intermediate form blocks are constructed in a novel manner, to the end that a wrapper may be expeditiously and properly secured in adhering relation to the exterior faces of a box of the desired character.

Referring particularly to Figs. 13, 15 and 16, the up r form block 23, which in the example s own is preferably of metal, is provided in two opposite parallel faces thereof with a channel or recess receiving an insert 45 to which a shoe 46 or the like is secured by a screw 47 or equivalent. Rising from the upper surface of form block 23, are the ears 48 or the like, pairs of which form bearings for shafts or rods 49 carrying, respectively, the form block (firesser members 50 comprising the upwar y extending actuating arm or lugs 51. Preferably, each presser member is biased in the direction occupied by the adjacent side of the box when on the upper form block structure by a coil spring 52, or equivalent Fi 15.

Referring to Fig. 16, it will be 0 served that the front face of upper form block 23 along its longer axis is provided with two resser members 50. Although not so shown, it shall be understood that the rear face thereof in parallel relation with said front face may be provided with a similar number of the presser members 50. Or, as a matter of choice, any other suitable numbers of such presser members may be utilized on the front and rear faces of said form block. It will also be observed that the face of form block 23 at the right, as viewed in Fig. 16, is provided with but one presser member 50. Obviously, the number of such members along said last-mentioned face of form block 23 may be varied as desired, as may the number thereof along the form block face in parallel relation therewith. Likewise, it is obvious that the number or position of the actuating lugs 51 may be varied as desired.

Assuming, for example, that a box of the eharacter illustrated in Fi 3 is to be wrapped with a wrapper o the character shown in that figure or in Fi 1, the box B is passed on to the interme iate and upper form block structure 22 and 23. Prior to the time thatsuch form block structure is thus positioned within the box, or immediately thereafter, the section a, Fig. 1, of wrapper W is caused to register with and adhere to the bottom B of the box. Thereafter, the upper and intermediate form block structures carry the bottom B of the box and section a of the adhering wrapper into engagement with the lower form block 44, whereupon the front and rear side panels 0 and d of the wrapper are folded, respectively, into engagement with the front and rear box walls B and B by the oppositely surfaces of the ,box ends B respectively,

adjacent the front and rear walls 0 the box, and the wrapper is cut or slit along the lines at and 3 Figs. 1, 5' and 5. These 0 erations may be, and preferably are, e ected substantially simultaneously.

To this end, I'may utilize a construction of the character illustrated in Figs. 9 and 11, wherein the groove G of cam 8 receives a roller 56 carried by a lever 57 comprising the oppositely extending arms 58 to which, respectively, are pivoted the links 59 in turn pivoted, respectively, to the members 60, each of which is secured to a shaft 61 mounted in suitable bearings carried by the bottom of table 4. At or adjacent their other ends, shafts 61 each carry a member 62 terminating, in the example shown, in a fork-shaped portion connected by a link 63 to a member 64 provided with perforations in which are received and secured the rods 65 mounted for reciprocatory movement in the slides 66. Each pair of the rods 65terminates in a transverse member 67 on which are adjustably mounted the corner-lap members 68.

The construction described above for controlling corner-lamp members 68 is well understood in the art. Cam 8 by its groove G functions to swing lever 57, Fig. 11, in a clockwise direction at the proper time during a pause in the descent of the partially wrapped box to move the corner-lap members 68 carried b the respective members 67 toward each 0t er along the box ends to wipe the corner-lapmsections into engagement therewith. A r such operations, cam groove Gr retracts said corner-lap members 67 until such time as another box descends through the machine.

Suitabl secured, as by the screws 69, to each of t e corner-lap members 68, is a U- shaped member 70, preferably of metallic s ring material, one arm of which is longer than the other and whose end is upturned, as indicated at 71, Fig. 17. Formed integrall by preference, with member 70 is the suhstantially plane knife-edge 72. As the various corner-lap members 68 move to ward each other along the box ends to perform the wiping operation aforesaid, the knife edges 72 at each box corner, cut or slit the wrapper along the lines w and y, Figs. 1, and 5, and substantially simultaneously with such cutting operation the rectangular sections 0 and d are folded into engagement with the upper horizontal surfaces of the box ends at the res ective corners. Immediately adjacent sue rectangular sections, the long arm of member 70 performs a creasing operation, whereby the rectangular sections a and d are left upstanding. The partially wrapped structure at this stage of the operation is as indicated in Figs. 5, 5 and 5.

Upon completion of the foregoing operation, further movement of the form block structure is initiated, and the partially wrapped box is carried downwardly between the brushes 73 and rolls 74, Figs. 9 and 10, to fold the end panels 6 into engagement with the respective ends of the box, the condition of the partially wrapped structure at this sta e of the operation being as indicated in igs. 6 and 6.

Groove G of cam 8 receives a roller 75 carried by a lever 76 pivoted intermediate its ends to an arm 77 carried by platform 3, Fig. 9. At or adjacent its other end, lever 76 is pivoted to a link 7 8 in turn pivoted to a cylindrical member 79 through which passes the tube 42 carrying the lower form lock 4A. Member 7 9 comprises four radiating cylindrical arms 80 disposed ninety degrees apart around the axis of member 79. Each arm 80 carries a rod 81, from each of which rises a member 82 reciprocatory in a bearing formed in an extension 84 of slide 66. A link 83 pivoted to each member 82 is likewise pivoted to a cam 85 controlling the plates or fingers for turning the upper wrapper sections inwardly.

The construction described above for controlling cams 85 is well understood in the art. Cam 8 by its groove G functions to swing member 76 on its pivot to thereby raise members 79 and rods 81 at the proper time dnrin another pause in the descent of the partia y wrapped box for moving the turn-in fingers toward the center of the box.

In accordance with my invention, there are provided novel turn-in fingers or members for foldin the turn-in sections of the wrapper inwar 1y into the position indicated in Fig. 7. To this end, I may utilize a construction of the character illustrated in Fi 13 and 14, wherein each cam 85 con tro s one or more rods 86. Secured to the rods 86 is a member 87 to which by screw 88 are secured the plates 89 supporting the ledge 90, screws 91, respectively, securing the plates 89 to ledge 90. Plates 89 are prevented from turning due to the fact that they engage the shoulder 87 on member 87. Plates 89 extend in opposite direction for supporting the hinges 92, to which are attached, respectively, the turn-in fingers 93 biased in a downward direction, as viewed in Fig. 13, by leaf spring 94 or the like.

It shall be understood that four turn-in structures comprising any suitable number of pivotally mounted sections, as turn-in fingers 93, are utilized for effecting the de scribed operation, and that two of such turnin structures are so mounted as to move toward and from each other over the respective horizontal top surfaces of the box ends in a direction at right angles to that in which move the other two turn-in structures co-acting with the front and rear box walls. In so doing, although the led es initially engage the turn-in sections of the wrapper, the folding operation proper is performed by the turn-in fingers 93 which, due to the biasing effect of springs 94, cause wiping or ironing of the wrapper sections 1), c and (1 into engagement with the horizontal top surfaces of the box walls.

Ledges 90, comprised in the various turnin structures, function primarily as a support for the upper form block 23, which, as soon as said ledges have moved into the position indicated in Fig. 13, is removed from the control of cam groove G and supported solely by said ledges.

At this time, the condition of the partially wrapped structure is as indicated in Fig. 7. Cam 85 having moved the turn-in structures toward the center of the box to the full extent permitted immediately acts in a reverse direction to retract such structures, and as the ledges 90 are Withdrawn from beneath the upper form block 23, that structure drops as a dead weight into the box and on to the intermediate form block 22 carrying the free portions of the now horizontally extending turn-in sections of the wrapper downwardly into adhering relation with the interior top surfaces of the box walls.

Thereafter, the wrapped box moves slightly downwardly to a position where pressure may be applied to the wrapper sections aforesaid freshly folded into engagement with the interior surfaces of the box walls. The wrapped box and a part of the associated pressure-applying mechanism is illustrated in Fig. 15, wherein a box-squaring or presser block 95 is supported in a housing 96 in turn supported in a member 97 from which rises a bearing 98 slidably supporting a rod or plunger 99 on whose stem is mounted a coil spring 100 or the like for biasing said plunger toward the right, as viewed in Fig. 15, to the extent permitted by the ad'ustment of nuts 101 on the threaded end '0 the plunger stem. Member 97 is 102, for the structure decomprises a also apertured, as indicated at reception of the turn-in fingpr scribed above. Presser bloc 9 stem 103 slidably mounted in aligned aperpoint 104 of substantial amount of pressure to the exterior box wall.

Due to the action of high point 105 on stem 103, member 97 is moved toward the right, Fig. 15, and'stem 99 enthe turn-in sections the box from said form block structure.

claims,

' indicates the cam gaged with lug 51 to thereby apply ress-ure to the wrapper surface just folded into en agement with the interior top surface of the hox wall, whereby such wrapper surface is caused to remain in intimate contact with the adjacent surface of the. box wall structure. 1 It shall be understood that mechanism of the character just described is mounted adiacent each wall of the box whereby in the ast stage of the wra pin operation all of reshl y folded into engagement with the upper interior surfaces of the box walls are gripped and squeezed between a presser member, as member 50, and a box-squaring or presser block, as member 95.

At the conclusion of the operation aforesaid, the form block structure immediately transports the wrapped box upwardly without pause until fingers 34 function to strip As well understood in the art, all of the various tools and instrumentalities have been withdrawn from the path of the fornfblock structure to permit such upward movement.
